I am familiar with this issue, they are are marking questions as duplicate when actually they are just related questions. And users intentionally not up voting. but at least in SE users are in good faith, encourage good quality answers & avoid duplicates.

I was talking about, this post being duplicated 4 times

I am sorry, my server(https://thelemmy.club/) got downtime, so clicked create post button multiple times to retry. I deleted them.
